UNITED STATES PATENT OFFICE.

JOHN OHABLESWORTH, OF CHICAGO, ILLINOIS.

SMOKE-CONSUMER FOR LOCOMOTIVES.

SPECIFICATION formingpart of Letters Patent No. 247,886,'dated October 4, 1881.

Application filed March 26, 1881.

To all whom it may concern: Be it known that I, JOHN GHARLESWORTH, a subject of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, United States of America, have invented a certain new and useful Improvement in Smoke- Oonsuming Attachments for Locomotive and other Engines, of which the following is a specification. I I

The object of my invention is to provide an attachment to a locomotive or other engine so arranged and connected that the smoke will beforced back into the fire and consumed without passing into the air.

My invention consists in the combination of a fan with a revolving crank in connection with a double smoke-chamber of an engineboiler. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a transverse section of a boiler and smoke-chamber with my fan attachments and connections ready for use. Fig. 2 is a sectional view of the same. Fig. 3 is a sectional view of the fan and fan-box. Fig. 4is a longitudinal section of the boiler with fan attachments, showing the fire-box and howthe smoke is conveyed and consumed.

Similar letters refer to similar parks throughout the several views.

A is a steam tubular boiler provided with tubes H ,H ,and H for the passage of the smokechamber, and tubes H H and H for the return of the smoke to the fire-box.

K is the smoke chamber or box in frontof boiler, it being of the same circumference as the boiler and forming part of the same. It is divided into an upper and lower chamber by the partition W, so that the tubes H, H and H will be in the upper, and the tubes El, H and H in the lower, chamber.

Bis a fan, made of four wings, as shown in Fig. 3.

O is a small iron box containing fan B. It

is placed in the center of the smoke-chamber K. It is made secure at its lower end by the' rod I, and is also attached or fastened to the partition W. The fan-box (lhas on its side the opening L, which is above the partition W, and at its lower end, in the lower chamber, it has the outlet M.

(No model.)

D is an iron shaft extending from one side of the smokechamber to the other, and running through the same. It is provided with bearings E E on the outside of the smoke-chamber, in which it revolves freely. The fan B is attached in the center of the smoke-chamber to the shaft D and revolves therewith.

G is an arm or crank, secured to the shaft D. It is connected with some motive power, either a small engine or any other motive power, and turns the shaft D, which revolves the fan B.

l is a bar or. rod in thelower part of the smokechamber, extending from side to side, and is a support for the fan-box O.

L is an openingin the side of the fan-box C. It is above the partition W, and is for the purpose of admitting the smoke from the upper chamber.

M is an outlet or opening in-the lower part of the fan-box 0, below the partition W, and is for the purpose of an outlet for the smoke from the fan-box O.

N is a bearing on one side of thefan-box O, for the shaft D.

0 is the same as N, except that it is on the opposite side.

P is the front end of boiler and rear Wall of the smoke-chamber.

R is the ash-pit of the furnace.

S is the fire-grate.

T is the fire-box.

W is a partition extending across the smoke box or chamber K, below the tube H and above H and divides the smoke-chamber K into an upper and lower chamber, X and Y. It has an openingin its centerfor the fan-box G,which is fastened or secured to it.

The above is a description of my improvement in connection with a locomotive-engine; but it may be used with stationary engines as well, it being arranged for the purpose.

The manner of operation is a follows: The crank G is connected with either a small engine or some other motive power, and the ICC C, and will then be propelled or forced out of the fan-box 0 through the opening M into the lower chamber, Y, through pipes H H and H into the ash-pit, and from thence into the fire, where it will be consumed.

I am aware that prior to -my invention fans have been used in connection with steam-boilers to consume the smoke by forcing cold air into the smoke-chamber. I therefore do not claim such combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is

The combination, with a furnace and a boiler having return-fines, ofa smoke-box divided by a partition,W, into upper and lower chambers, 15

I, and the fan beingjournaled on a revolving 2o shaft, D, provided with a crank, G, substantiully as and for the purpose shown and described.
